  • Tough
  • Durable
  • Zero upkeep

Install it once. Enjoy it forever.

Unlike wooden sheds, our storage units won’t rot, warp, or require repainting. Manufactured from PVC-coated galvanised steel, they’re built to withstand the elements with minimal effort from you. There’s no need for regular treatments or repairs — just long-lasting performance backed by a 25-year panel guarantee against rust perforation. It’s reliable, hassle-free storage that won’t let you down.

“I bought one of your fab bike sheds back in May and we built up in June. I built it by myself, with just a bit of help needed to slide the top roof part on. Very proud of myself I was! Only getting around to sending you these pics now – we’re loving our shed.”
